A Viennese apartment building, KAM, was built in 2007 to minimum passive house requirements primarily designed to
perform for heat conservation in winter. Less emphasis was placed on cooling in the warm months when planning the building
due to the temperate continental climate of Vienna, Austria. Due to apartment owner complaints of overheating, exterior blinds
were installed on apartment windows and doors on the topmost floor. Indoor temperature and humidity in four apartments have
been monitored over three summer periods. The monitoring results are presented where mechanical ventilation with heat recovery
is used in combination with exterior sun shading. The users in the case studies prefer using natural window ventilation to changing
ventilation system settings. Indoor daily temperatures remain constant when windows are left closed and shading is used. Results
frommonitoring and interviewsindicate the importance of consideringsummercooling strategies in combination with user behavior
in highly insulated buildings to control overheating in summer.
